I think one of the reason Paul wrote not to be concerned or obsessed with Sabbaths and feast days is that the Holy Spirit well knew that the original calender or ability to keep track would be lost. Even the Jews were unable to accurately keep track. This “age of grace” is just that, an “age of grace”. This series of blood moons may just be God’s way of getting them back “in sinc” for the coming last seven years.
